Is this math? I'm sorry I don't get what formula I'm supposed to rewrite or -
Answer:
1. 91 = 70*1.30
2a. 195= 150*1.30
2b. 210 = 150*1.40
3a. 56.70 = 156* .30
3b. 132.30 = 156-56.70
3c. 17.20 = 132.30 *0.13
3d. 149.50 = 132.30+17.20

Try this option:
1. rule: cosα=sin(90°-α), it means that cos 3x=sin(90°-3x);
2. sin(90°-3x)=sin(x+18°); ⇔ 90°-3x=18°+x; ⇔ x=18°.
Answer: x=18°.
